JAcKET'FoR ROLLS.

'1"; all whom it may concern.-

Be it known that I, CLAUD'D. FRANCE, a citizen of the United States ofAmerica, residin at Vandergrift, in the county of Westmore and and Stateof Pennsylvania, have invented certain new and useful Im rovements inJackets for Rolls, of which t e following is a specification, referencebeing had therein to the accompanying drawings.

This invention relates. to certain new and useful improvements in rolls,and more par ticularly to a jacket adapted to be mounted upon saidrolls.

The invention aims to provide a jacket which can be readily -mountedupon the necks of a roll to protect the same when bein cooled.

he neck of a roll when revolving within its housing becomes heated bythe frictional contact of the neck with the brass boxes, and this heathas a tendency to fuse the neck of the roll, distort the same, interferewith the rotation of the roll, and finally render the same useless. Inrollin -mills the heat enerated by the rotation o the necks of a r0 1 isreduced considerabl by feeding cold water upon the same, an this mannerof cooling the necks of a roll has also proven to be injurious to thenecks and to finally ruin the material from which the necks are formed.:By the provision of a novel form of metallic jacket, which is composedof brass or other suitable and substantially non-.oxydizable metal andwhich can be fitted over the neck of a roll and will turn therewith,Lhave de vised means for preventin water from contacting with the neckof t e roll while it is being cooled, and the many advantages of myimproved jacket will be a parent to those skilled in the art ofmanipulating rolls.

Another object of my invention is to provide a device wherein thelubricant may be economicall used. In rolls of this character when t esame become highly heated much grease or other lubricants are consumed;but with my improvements the cost of lubricants is reduced to a minimumand a great saving is accomplished.

It will also be noted that I obtain a feat savin in the wearing of thejournals an the breaking of the same, such as a savin of Babbitt metal,bronzes, brass, and the ike, that is used in the journals for the necksof the rolls.

With the above and other objects in view the invention finally consistsin the novel Specification of Letters Patent. Application filed February9.1905. Serial No. 244-986.

Batented Jury 24, 1906.

construction, combination, and arrangement of parts, which will behereinafter more fully described and then specifically pointed out inthe claims, and, referring to the drawings accompanying thisapplication, like numerals of reference designate corresponding partsthroughout the several views, in

which Figure 1 is an end view of a roll. Fig. 2 IS a side elevation viewof a portion of a roll. Fig. 3 is an end view of my improvedjacket. Fig.4 is a vertical sectional view of the same; and Fig. 5 is a sideelevation view of a portion of a roll, illustrating my improved jacketmounted upon the neck thereof.

To put my'invcntion into practice and to demonstrate the practical useof my improved jacket, I have illustrated the same as eing used inconnection with a roll 1, havin a neck 2 and'a wabbler 3. v

y improved jacket consists of a sleeve or collar 4, having a flared end5. The opposite end of the jacket is partially closed, as indicated at6, this end being formed with an opening 7, said opening having acontour substantially that of the wabbler 3 in crosssection. The jacketis also rovided with an annular flared flange 8, which forms ashelf forprotecting the coupling-box, which is connected to the wabbler 3. Thejacket is ada ted to be mounted upon the neck 2 of the r0 1, asillustrated in Fi 2.

of the drawings, and it will be observed t at the flared end 5 of thejacket fits neatly upon the neck and in close proximity to the bodyportion of the roll 1.

The jacket, as hereinbefore stated, is adapted to turn with the neck ofthe roll and is formed of brass or other suitable and nonoxidizablematerial, the jacket and the roll turning togetherin the housin Thepartiall -closed end 6 o the jacket is adapted to em race the end' ofthe neck and the wabbler 3, and when the wabbler is mounted in acoupling-box the annular flange 8 is adapted to engage the coupling boxand prevent the water that may be sprayed upon the jacket from enteringthe cou ling-box.

improved jacket protects the necks of a roll from the water that issprayed upon the same, and as the jacket receives the water it is cooledand gradually cools the neck of the roll 2 and" prevents the materialfrom which the neck is formed from being injured. The annular flange 8prevents any water from passing onto the wabbler 3, and as theconstruction of my im roved 'ackets is extremely simple they can e reaily renewed from time to time without incurring any considerableex ense.

It wi 1 be noted that various other changes may be made in the detailsof construction without departing from the general spirit and scope ofthe invention.

' What I claim, and desire to secure by Letters Patent, is

1. A jacket for rolls comprising a collar havin a flared end, the oposite end of said collarfiming partially closed and an annular flangecarried by said end, substantially as described.

2. In a device of the t p0 described, the combination with the necl isof rolls, ofjack-' ets ada ted to fit u on said necks and having one en'partiall c osed, the opening therein conforming to t e shape of andbeing adaptturn therewith, and havin an annular flange adjacent saidpartially-c osed end thereof,

substantially as described.

3. The combination with the .neck of a roll, of a jacket adapted to fitu on said neck, said jacket having a partia y-closed end ada ted toembrace the wabbler of said roll, sai jacket being connected with theroll so as to turn therewith and means carried by said jacket to protectsaid wabbler from Water sprayed upon said jacket, substantially asdescribed.

i In testimony whereof Iafiix my signature in the presence of twowitnesses.
